    Subject line should read, what's wrong with this...

    Hmm...

    The following works for me.... 
    <operator name="Root" class="Process" expanded="yes">
        <operator name="DatabaseExampleSource" class="DatabaseExampleSource">
            <parameter key="database_system"	value="Microsoft SQL Server (Microsoft)"/>
            <parameter key="database_url"	value="jdbc:sqlserver://localhost:1433;databaseName=Tradestation"/>
            <parameter key="username"	value="sa"/>
            <parameter key="password"	value="wL8/6ZO7YrXKa8XgQd4v7g=="/>
            <parameter key="query"	value="SELECT  FROM [Updates]&#10;where O &lt;100"/>
        </operator>
    </operator>
    So your point is what, exactly?

    Thanks, the SQL seems to work but I do not see the output file.

    Ah, I see, this has nothing to do with...
    less than '<' in SQL querry string is fatal

    Hi,
    if I see this correct, you have the problem, that the model file isn't written? Then you should simply start the process. Otherwise non of the operators is executed.

    Greetings,
      Sebastian
